I will probably try
actinic for 12 and daylight for 10 and see how that goes then.
I think I may try a rotation schedule for bulb changes. With 6 bulbs, I will change one
actinic and one daylight every 4 months. That will be a full year for each bulb which is a little longer than most seem to use them, but at the same time I will have a couple fresh ones in there too. And I can keep the first changeouts (that don't get a full year) around for spares.
I habe einen noch langer tag gern, aber es kosten mehr elektric und lichten.
